Have you ever stopped to think about how your daily habits might be quietly shaping the health of your brain? As a neurologist, I’ve spent years studying the intricate workings of the mind, and I’ve seen firsthand how seemingly harmless routines can impact memory, focus, and long-term cognitive health. While most of us know the basics—eat well, sleep enough, exercise—there are other common practices that could be silently undermining your brain’s potential. Let’s dive into four everyday habits I steer clear of to keep my mind sharp and why you might want to reconsider them too.
Habits That Harm Your Brain: A Neurologist’s Perspective
It’s easy to fall into routines that feel convenient or harmless, but as someone who’s seen the effects of neurological decline up close, I’m careful about what I expose my brain to. The choices we make daily don’t just affect our energy levels or mood—they can shape the structure and function of our brains over time. Below, I’ll walk you through four habits I avoid, backed by science and sprinkled with a bit of personal insight, to help you make informed decisions for your own mental wellness.
1. Over-Reliance on GPS for Every Trip
Picture this: you’re heading to a new coffee shop across town, and your first instinct is to punch the address into your phone’s GPS. Sound familiar? While GPS is a lifesaver for avoiding traffic jams, leaning on it for every journey might be dulling your brain’s natural navigation skills. Spatial memory, the part of your brain that helps you map out routes and remember landmarks, thrives on practice.
Research shows that professions requiring heavy navigation—like taxi drivers—tend to have larger hippocampi, the brain’s memory hubs. A study even suggested that these drivers may have a lower risk of Alzheimer’s disease because they constantly challenge their spatial skills. On the flip side, always outsourcing your navigation to an app could weaken this critical brain function over time.
Navigating without GPS engages your brain in ways that keep it sharp and resilient.

I’m not saying you should toss your phone out the window. Instead, try this: next time you’re heading somewhere familiar, turn off the GPS and rely on your memory. Or, when exploring a new place, take a moment to study the route beforehand and use landmarks to guide you. It’s like a mini-workout for your brain, and trust me, it feels satisfying to get there on your own.
- Challenge yourself to navigate short trips without GPS.
- Use mental maps or landmarks to reinforce spatial memory.
- Explore new routes to keep your brain engaged.
2. Chugging Energy Drinks for a Quick Boost
We’ve all had those days where we’re dragging, and a brightly colored energy drink seems like the perfect pick-me-up. But as a neurologist, I can tell you these cans are trouble in disguise. Packed with caffeine, taurine, and sometimes excessive B vitamins, energy drinks can wreak havoc on your nervous system if you overdo it.
High doses of caffeine can lead to insomnia, anxiety, and even heart palpitations. In rare cases, I’ve seen patients experience seizures tied to excessive energy drink consumption. Then there’s the lesser-known issue of vitamin B6 toxicity. Unlike most water-soluble vitamins that your body flushes out, B6 can build up and cause nerve damage, leading to symptoms like tingling or numbness—something called peripheral neuropathy.
In my experience, people often underestimate how much caffeine they’re actually consuming. A single can might have more than a cup of coffee, and if you’re downing multiple a day, you’re rolling the dice with your health. Instead, I opt for water, herbal tea, or a quick walk to re-energize. It’s less glamorous, sure, but your brain will thank you.
| Drink Type | Caffeine Content (mg) | Potential Risks |
| Energy Drink | 80-300 | Anxiety, palpitations, B6 toxicity |
| Coffee (8 oz) | 95-200 | Moderate risk if overconsumed |
| Green Tea | 20-45 | Low risk, antioxidant benefits |
Next time you’re tempted to grab an energy drink, ask yourself: is this quick fix worth the long-term risk? A balanced diet and proper hydration often do the trick without the neurological downsides.
3. Popping Over-the-Counter Meds Without a Second Thought
It’s easy to reach for an over-the-counter (OTC) painkiller or antacid when you’re feeling off. After all, they’re readily available, so they must be safe, right? Not quite. As a neurologist, I’ve seen how overusing OTC medications can lead to surprising and sometimes serious consequences for your brain and body.
Take NSAIDs like ibuprofen or aspirin. Overuse can cause stomach ulcers, kidney issues, or even chronic conditions. Then there’s acetaminophen, the active ingredient in Tylenol, which is notorious for causing liver failure when taken in excess. I’ve also encountered rare cases where excessive use of certain OTC products, like those containing bismuth, mimicked dementia symptoms. Scary stuff!
Just because it’s over-the-counter doesn’t mean it’s risk-free.

One patient I worked with developed neurological symptoms after following an online trend of taking high doses of zinc supplements. The result? Spinal cord damage that could’ve been avoided. My rule of thumb: stick to the recommended dose, check with a doctor if you’re using something regularly, and be wary of wellness fads promising miracles.
- Always read and follow medication labels.
- Consult a healthcare provider for frequent use.
- Avoid unverified supplement trends from social media.
4. Venturing Outdoors Without Protection
I love a good hike as much as anyone—there’s nothing like fresh air to clear your mind. But heading into nature without taking precautions can expose you to risks that go beyond a sunburn. Tick-borne illnesses and mosquito-borne diseases are more common than you might think, and they can have devastating effects on your brain.
Every summer, I see patients with symptoms ranging from fever and confusion to seizures or coma, often linked to infections like Lyme disease or West Nile virus. These conditions can sometimes cause lasting neurological damage if not caught early. The good news? A few simple steps can drastically reduce your risk.
Personally, I never hit the trails without bug spray, long sleeves, and a post-hike tick check. It’s a small price to pay to avoid potentially life-altering infections. Plus, knowing your surroundings—like whether ticks or mosquitoes are common in the area—can make all the difference.
- Use insect repellent with DEET or picaridin.
- Wear protective clothing in wooded areas.
- Check for ticks after outdoor activities.
Why These Habits Matter for Your Future
Your brain is like a finely tuned machine—it needs care and attention to run smoothly. The habits I’ve outlined might seem minor, but over time, they can add up to significant risks for your cognitive health. By making small changes—like navigating without GPS, swapping energy drinks for healthier alternatives, being cautious with OTC meds, and protecting yourself outdoors—you’re investing in a sharper, healthier mind for years to come.
In my practice, I’ve seen how proactive choices can make a difference. One patient, after cutting back on energy drinks and starting to navigate her city without GPS, reported better focus and even a sense of accomplishment. It’s not about overhauling your life overnight but about making mindful tweaks that add up.
Small changes today can protect your brain for tomorrow.

So, what’s the takeaway? Your brain is your most valuable asset, and it’s worth protecting. Next time you reach for that energy drink or plug an address into your GPS, pause and consider: is this habit helping or hurting my mind? A little awareness goes a long way.
